PROBLEM TO BE SOLVED: To reliably obtain a reciprocation motion of a piston magnet while improving the reciprocation continuity, thereby obtaining a continuous rotational power.SOLUTION: A rotational power producing device 100 has first and second piston magnet members 60 and 61, a crank shaft 11, first and second guide members 50 and 51, first and second stationary magnet members 70 and 71, and first and second demagnetization rotational drums 30 and 130 provided with first and second demagnetization cylindrical bodies 32 and 132, respectively. Between the first and second piston magnet members 60 and 61 and the first and second stationary magnet members 70 and 71, upper pole surfaces 60a and 61a and stationary pole surfaces 70a and 71a with the same polarity are arranged to face to each other. The first and second demagnetization cylindrical bodies 32 and 132 have a demagnetization magnet part 38 and 138 with a magnetic force which is weaker than magnetic poles of the upper pole surfaces 60a and 61a and has a different polarity from the upper pole surfaces 60a and 61a, and a non-magnetic force part 39 and 139, respectively. |
